CVE-2019-6109: Due to missing character encoding in the progress
display, a malicious server (or Man-in-The-Middle attacker) can employ
crafted object names to manipulate the client output, e.g., by using
ANSI control codes to hide additional files being transferred. This
affects refresh_progress_meter() in progressmeter.c.
CVE-2019-6111: Due to the scp implementation being derived from 1983
rcp, the server chooses which files/directories are sent to the client.
However, the scp client only performs cursory validation of the object
name returned (only directory traversal attacks are prevented). A
malicious scp server (or Man-in-The-Middle attacker) can overwrite
arbitrary files in the scp client target directory. If recursive
operation (-r) is performed, the server can manipulate subdirectories as
well (for example, to overwrite the .ssh/authorized_keys file).

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
